be substantially non-flying, and to provide means for securing straps of ductile metal special form of non-flying charge-holding case wherebyV it may be held to the head of a rail.

These and other features of my invention are more fully described hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is a view showing a torpedoembodyng my invention in position upon the head of a rail.

Fig. 2, is a perspective view of the torpedo before application to a rail head.

3 is a plan view of one end of the torpedo showing the rail engaging strap connected thereto.

Fig'. 4, is a sectional view on the line IV-IV, Fig. 3.

Fig. 5, is a perspective- View of part of a shell or container for the explosive charge, made of rubber, rubber-containing, or other homogeneous material.

Figs. 6 and 7, are views illustrating another form of connection for the rail-engaging` strap Within the scope of my invention.

Figs. 8 and 9, are views illustrating one nianner of preparing retaining straps to be secured to the torpedo for holding the same to the head of a rail, and

Figs. 10 and 11, show forms of heads.

In the form of structure illustrated in VFigs. 1, 2, 3, et seq., 1 represents a shell or container for detonating material, Which may be of paper', friction cloth or any other suitable form of textile or knitted fabric, or any other suitable material, adapted to contain a detonating charge straps With other character prepared 1n any suitable manner;

ductile metal, passed; such strap `having f p :may comprise side projections 6 whereby it may be retained in placeiby the i material constituting the casin` the container, or otherwise, and ``ends so prepared may then be ierwise secured to said In Or shell of the folded own apmolded conrubber-containing, or other homogeneous material, having ends 3 apertured at 4 through Which the headed retaining may be passed; such molded structure being otherwise capable of performing the same functions as the l/V hen fastening means such 8 or rivets 9 are employed, the passed through an aperture in the of the torpedo, as in. the structure shown in .Figs 1, 2, 3, et seq.; such arrangement being illustrated in Fig. 6, Where an eyelet fastener 8 is shown. In lieu of this, the

folded end as the eyelets i strap may be strap may be on the inside of the folded end he torpedo, as shown in Fig. 7, where a rivet 9 is employed as the fastening member. Both eyelet and rivet may be of ductile metal so as to reduce the possibility of injury should eitherfly on explosion of the torpedo.

The lead straps 5 which are attached to the torpedo for engagement with the rail head may be cut from solid sheets of lead in the manner indicated in Figs. Sand 9; the method of cutting providing extended ends to form heads Which Will be hel'd hy the folded end of the container, or the fastening means described, in the manner shown in the drawings. (o I'n the form of strap 'shown in Fig; 8, th'e side extensons 6 are at rightV angles to the main body of the structure, While in the form shown in Ei'g'. 9, such extensions are shown as 'unde'rcut by recessing' the 'same adjacent the main body of the strap, as indicated at 3. Other forms of hea'ds 'are shown in Figs. 10 and 11; that of Fig. 10 being r'onnd, While that of Fig. ll, is Wedge-'shaped7 and such forms .may be 'cnt from solid sheets in the same nianner as illustrated inFigs. 8 and E). Afnv snitahle form of strap attaohable t'o theJ ends of the torpedo and capable of performing the desired function, I deem to be Within the s'c'op'e of my invention.

I claim: 1. The combination, in a track torpedo, of

a shell or casino; containing an explosive charge and having folded ends, means for secnrinfl'u said ends in folded condition7 and rail-enga'ging 4stiaps of ductile metal for holing the torpedo to a rail head Secured to said folded ends; said strap's having enlarge heads retainedin the folds of said 'container ends. I

2. The c'ombinaton, in a track torpedo, of laY containe'r having fold'e'd ends, apertures in tli'e folds of saidends, headed rail-engaging` straps adapted to said apertures and held to the c'ontaihe'i` said heads, and means for se'curing th'e folded ends of the eontainer to hold the 'st'iaps 'against displacement.
